Why did you do that?

Why did we do that? Well, I suppose it was partly in my blood, in the sense that during my first year at medical school, I spent a lot of time not studying so much, but building a giant mammoth, which we then hauled down New Street in Birmingham during the carnival and had a wonderful time.

I virtually failed my anatomical exams at the time, but scraped through medical school eventually.

After some years, I joined Rotary and it was...

It's drawn my attention that a man called Roger Frank in Eden Vale Rotary Club up in the north had constructed a working model of an iron lung, which he had set up in a trailer.

And we were intrigued by this and we borrowed it and hauled it all the way down to Thornbury and set it up outside Thornbury Tesco's.

and raised about £1,000 in a weekend.

And that's such an important distinction, isn't it? It's separating the mosquito as part of the food chain and a very important part from that malaria parasite.
